Kim Kardashian just gave birth to her tiny daughter, North West, on June 15. Though the little one is the first child for Kim and boyfriend Kanye West, she’s not the first grandchild in the Kardashian family.

Kim’s sister Kourtney Kardashian already has two kids, which means that North will grow up with two cousins very close to her age. But just how close in age will the kids be?

Kourtney’s youngest, Penelope Scotland Disick, is only 11 months old, which means she and North will be less than a year apart. Can you imagine all the adorable playdates? The matching leopard print designer outfits? Nori and Penelope are going to be the most adorable little cousins in the world.

Penelope’s older brother, Mason Dash Disick, will be a bit older than the other two. At 3 1/2 years old, we bet he’ll hit an age where he thinks he’s too cool to play with the little kids. Still, the age is close enough that we’re sure he’ll be around to hang out.

Plus, it’s not like there will be a shortage of family members around. We’re willing to bet that aunties Kendall, 17, and Kylie, 15, will get called on to babysit all the time. As long as they don’t spoil the little ones with too many quirky, oddball gifts...
